Merit Granular (by Bayer) is the longest lasting broad-spectrum grub control product on the market. Both curative and preventative, Merit Granules holds a ten-year record of 90% effectiveness on virtually every species of turf and ornamental pests. Merit even improves the quality of your turf. Merit 0.5 G is for broadcast application on and around turfgrass, ornamentals, trees, shrubs, flowers, groundcovers, and in and around commercial or residential buildings. Apply Merit 0.5 G uniformly over area being treated with normally used granular application equipment. Both drop-type and rotary-type spreaders may be used. Avoid using a spreader which would apply the product in narrow bands. For optimum control, product application should be followed by mechanical incorporation, irrigation, or rainfall, to help move the active ingredient into the soil.
MERIT is most effective when applied prior to, or just after, egg lay. In most cases, adult emergence occurs in early summer, often after significant rainfall or irrigation, followed by mating and egg laying. This usually continues for four to six weeks. Under normal circumstances, Merit will provide residual white grub control for four months or longer in turf.
Grub control that works
By Jim on 04/04/2011
I have spent hundreds of dollars on different grub control products each year with the same result: grubs. Last year I discovered the 0.5 G Merit and thought that the extra strength might get it done. After years of frustration, this product worked as advertised.

This stuff works
By Doug on 09/09/2012
I've been fighting with white grubs destroying my marathon 2 lawn for several years and had tried several products before, but they barely slowed down the spread. After one application of the Merit Granules the spread of the dead areas has ceased and visible recovery has begun. If you have white grubs, this stuff works.

best product ever
By David on 09/18/2010
last year i awoke to find my yard over run by crows. During the day i would run outside and chase them away but they would return within the hour. The crows were destorying my lawn. So i called a professional lawn service and they promise to treat and end the problem. The day after the lawn was sprayed the crows continued tearing up my lawn. Even after a month later. At that point i searched the internet and found a product called" crowbegone". A cd with strange bird calls but after a month of use it to was a failure. The crows had won so i thought. Thats when i came across your wed site and purchase Merit G. In two words "It Works ". After chasing away the crows i applied Merit G and watered it in real good that evening. Within the first week i observed fewer crows on my lawn. By the second week the crows would land on the lawn and walk around looking for their grub meal but the kitchen was closed. After a month only one or two crows would check out the lawn and then walk away. Problem solved. Now my lawn is beautiful again. THANKS.

White grubs and chinch bugs
By Clarence on 07/03/2011
I have used this product now for several years and find that it is the only way to control my problem bugs. "Do My own Pest Control" has been a Godsend for me. Im able to afford to continue treating with Merit 0.5 granules and shipping was free. Im so happy I found "Do My own Pest Control". I plan on doing business with you for many years to come. Thanks Docmoss

Merit Granules was recommended by the Maryland Agriculture Extension. I have not tried it yet, but this recommendation speaks for itself.

How many years does Merit last in the bag ? If it kills all the grubs in the first year, how many years do I have to use up the rest of the bag as a preventive measure before it goes bad. Do you ship to Ontario, Canada ? Thanks
I have a 57x53 ft. back yard ,front is about the same and have a terrible problem with grubs. I have used the bayer 24 hour kill in may and imacloprid in fall and still have a problem .I need to kill the ones that are hibernating from last fall and then the ones after egglay in august. I will be buying a bag of Merit but how long is the shelf life. and can I store it in the garage,I know to keep it clean and dry but will the cold affect it?
